Aviation Maintenance

Understanding Turbine Engines A Complete FAA A&P Powerplant Study Guide Based on concepts from the FAA Aviation Maintenance Technician Handbook – Powerplant (FAA-H-8083-32). Introduction Gas turbine engines are the primary powerplants used in modern commercial, military, and many business aircraft. Their high power-to-weight ratio, reliability, and ability to operate efficiently at high altitudes make them ideal for aviation. Unlike reciprocating engines, turbine engines operate on the Brayton Cycle, where air flows continuously through the engine rather than being drawn into individual cylinders. ...

Physics in Aviation: The Science Behind Aircraft Maintenance Physics is not just something pilots learn in ground school. It shows up everywhere in aviation maintenance: flight controls, hydraulics, fuel systems, propellers, aircraft structures, sheet metal repairs, torque values, weight and balance, and troubleshooting. For an A&P mechanic, understanding physics helps connect what is happening in the airplane to why a component is designed, inspected, adjusted, or repaired a certain way. ...

Studying FAA regulations for the A&P certificate can feel overwhelming at first. There are a lot of regulation numbers, and many of them sound similar until you understand what each one is actually used for. In class, these are often called FARs, meaning Federal Aviation Regulations. Technically, they are found in Title 14 of the Code of Federal Regulations, usually written as 14 CFR. So when someone says FAR Part 43, they usually mean 14 CFR Part 43. ...

Math for A&P Students: The Formulas You Actually Need to Know A lot of A&P students get nervous when they hear the word math. That is understandable. Aviation maintenance math can show up in several different areas: weight and balance, electrical circuits, torque, measurement, area, volume, ratios, percentages, and unit conversions. The good news is that A&P math is not advanced math. You do not need calculus. You do not need complicated algebra. What you need is a solid understanding of the basic formulas that aircraft mechanics actually use. ...

A&P Math: The Formulas Every Aviation Maintenance Student Should Know Math can make a lot of A&P students nervous, but aviation maintenance math is usually very practical. You are not doing math just to do math. You are using it to solve real aircraft maintenance problems. As an A&P student, math shows up when you are working with: Electrical circuits Weight and balance Torque values Sheet metal layout Hydraulic pressure Fluid quantities Temperature conversions Measurements Engine calculations Aircraft drawings and dimensions The good news is that most A&P math uses the same basic skills over and over: fractions, decimals, ratios, percentages, formulas, and unit conversions. ...

Aircraft Hydraulic Systems: The Basics Every A&P Student Should Know Aircraft hydraulic systems are one of those topics every A&P student needs to understand because hydraulics are used all over the airplane. Depending on the aircraft, hydraulic power may be used for landing gear, brakes, flaps, flight controls, spoilers, nosewheel steering, thrust reversers, cargo doors, and other heavy-duty systems. The basic idea is simple: hydraulics use pressurized fluid to transmit force. ...
